Cellulose decomposing strain CX10 from termite gut and application thereof

Abstract

The invention discloses a cellulose decomposing strain CX10 from a termite gut and application thereof. The strain is preserved in the General Microbiological Center of China Committee for Culture Collection of Microorganisms at the No.3, first yard, Beichen west road, Chaoyang district, Beijing, and the preservation number is CGMCC No.16344. The strain is a gram-positive bacillus and free of capsules, endogenous spores can be seen after spore staining, the bacterial colony is a single one and in a cracked shape, the bacterial colony is white, and the edge of the bacterial colony is complete.The strain is a facultative anaerobic strain for producing cellulase; within 48 hours, the FPA enzyme activity of the strain is 49.5 U/mL, the CMCase enzyme activity is 95.0 IU/mL, and the CX enzyme activity is 23.26 IU/mL. The strain is very high in biodiversity value, and has a scientific value of further research on cellulose-enriched crops and development and application of a traditional Chinese medicine fermentation recycling.

Description

technical field [0001] The invention relates to a cellulose degrading bacterium CX10 from termite intestinal tract and application thereof. Background technique [0002] Lignocellulose is the main structural component in the plant cell wall. It is composed of lignin, cellulose and hemicellulose, which are covalently bonded to form a spatial network structure. Due to its large molecular weight, complex structure and stable properties, lignocellulose is extremely difficult to decompose under natural conditions. In my country's agricultural production, various lignocellulose-rich crop straws, economic crops and medicinal plant waste resources are abundant and the output is huge. However, for a long time, due to factors such as lifestyle, processing technology and poor feedability, a large amount of crop straw and medicinal plant waste have been discarded or burned, and have not been rationally developed and utilized. According to the survey, the utilization rate of straw in o...

Problems solved by technology

The research barrier of the termite intestinal symbiosis system is the isolation and cultivation of a large number of intestinal microorganisms. Given the strict environmental conditions required for the survival and reproduction of intestinal bacteria, culture techniques are often not suitable for their research
